Tg(SLC18A3-cre)AMisa (RBRC01516) は、ヒトの小胞アセチルコリントランスポーターのプロモーター領域を含む11.3 kbのゲノム断片を用いたCre-driverラインである。脳と脊髄の体性運動ニューロン (約50%) 及び内側手綱核の一部で生後に Cre recombinase を発現する (Misawa et al., 2003)。前脳基底部、線条体、脳幹や自律神経など、その他のコリン作動性ニューロンにはCre発現は認められない。Cre発現は生後7日頃から始まり、数ヶ月から半年で最大レベルに達する (slow completion) 。これに対し、類似ラインであるTg(SLC18A3-cre)KMisa (RBRC01515) は数週間で最大レベルに達する(fast completion)。運動神経のサブタイプマーカーを用いた再評価の結果 (Misawa et al., 2016)、赤筋 (遅筋; タイプI, IIa筋線維) に投射するSlow運動ニューロン (SおよびFRタイプ)にCre発現の選択性が認められた。このため、本マウス系統の名前 (通称名) をVAChT-Cre.SlowからVAChT-Cre.Lateに変更した。参考文献:Genesis, 54, 568-572 (2016).

Tg(SLC18A3-cre)AMisa, RBRC01516, is a transgenic Cre-driver mouse line, in which Cre expression is driven by the 11.3 kb human vesicular acetylcholine transporter (VAChT) promoter (Misawa et al., 2003). The lines showed restricted Cre expression in approximately one half (40-60%) of the postnatal somatic motor neurons and cholinergic neurons of the medial habenular nucleus. Transgenic expression was not observed in visceromotor or other central or peripheral cholinergic neurons. Cre expression began on approximately postnatal day 7 and reached at maximal levels by several months of age (later onset than Tg(SLC18A3-cre)KMisa, RBRC01515). Re-evaluation (Misawa et al., 2016) of the line by using subtype selective markers showed preferred Cre expression in slow-type motor neurons (S- and FR-type) innervating type I or IIa muscle fibers. To avoid confusion the common name of the line was changed from VAChT-Cre.Slow to VAChT-Cre.Late. Ref. Genesis, 54, 568-572 (2016).
